Tamiya – GP RTR Nitrage 5.2 – 4×4 Racing Truggy

Introducing Tamiya’s new 1/8 R/C Truggy, the Nitrage. This high-performance Ready-To-Run model is packed with innovative features that no other machine in its class has. Modular construction means effortless assembly and convenient maintenance, with all the internal components mounted on a high-strength, press-molded aluminum deck. Servos are directly connected to the fully-enclosed gearboxes to ensure consistently smooth operation and minimal interference. 4-wheel independent suspension with large oil dampers, aluminum slipper clutch, and high-density spike tires mounted on large dish wheels lets it tackle any terrain with ease. The aggressive body and distinctive rear wing matches the “Nitro Rage” image perfectly and will make it the instant center of attention wherever it goes.

POWER AT YOUR FINGERTIPS

The Nitrage is equipped with the formidable FR-32FX 5.2cc engine that features a large diameter slide carburetor, 14mm diameter crank shaft, lightweight piston, and large heat sink head. The FR-32FX is matched with a 150cc large capacity fuel tank to provide ample driving endurance. Powered by this monster engine, the Nitrage with standard 1-speed transmission is capable of speeds of up to 60km/hr (approx. 37mph)!

Off-road racing often means dirt and grime accumulating on the vehicle and interfering with maintenance, to say nothing of all the work you have to do to clean up afterwards. Our designers took this into account when creating the Nitrage and separated the vehicle into 5 major components: Front Gearbox (with steering servo and front suspension), Center Gearbox (with throttle servo and disc brake), Mechanics Box (with fail safe equipped receiver), Engine with Fuel Tank, and Rear Gearbox (with rear suspension and wing). Each of these can be individually removed from the chassis for easy maintenance and cleaning. All 5 components rest on a special high-strength aluminum deck, a pioneering feature for this class, that was press-molded to ensure structural rigidity.

ALL GEARS FULLY ENCLOSED

Tamiya is the first to bring this special feature to the R/C world. Even the connection between the engine clutch bell and the spur gear are completely enclosed and protected from outside interference. As a result, all gears have constant stable lubrication and gear backlash is contained by the gearcase. This means the Nitrage does not need to resort to using any heavy and expensive steel gear parts, giving fans more modification flexibility.

Furthermore, the differential gear on the Nitrage is doubly protected, first by its own durable case and then by a second enclosure formed around it by the front and rear gearboxes. This setup insulates the differential gear to prevent the suspension arms and shock towers from imparting stress on it (this is the problem with most makers’ truggy differential gears).

EFFICIENT POWER TRANSMISSION

The Nitrage is equipped with the R/C world’s first flexible joint drive system, with the spur gear having a short dog bone linkage to the clutch bell, which helps reduce stress on the engine. A durable lightweight aluminum slipper clutch to improve transmission efficiency is also included, which is another first in this class.

WIDE-SPAN FRONT SUSPENSION UPPER ARM

Truggies from other makers usually feature upper I arms for the front suspension, which offer flexibility but are lacking in structural strength. The Nitrage has specially designed upper A arms for the front suspension that allow flexible suspension travel without sacrificing strength.

WHEELS & TIRES

Colossal off-road tires with inner sponge feature an oval spike tread pattern that is perfect for driving on rough surfaces. Tires are mounted on large diameter dish wheels.

DISTINCTIVE REAR WING

The large rear wing on the Nitrage is a double-split design inspired by those equipped on actual WRC cars. Catch pin attachment means the upper surface of the wing remains flat, adding to its stylish appearance. Since the wing is connected to the chassis and not the body shell, it clearly distinguishes the Nitrage as a Tamiya product even when the body is removed.

FOR ADDED CONVENIENCE AND INSTANT ACTION

The Nitrage features universal screw heads for most of its screws, which means all you need is the 2.5mm Hex Wrench to attach and remove them, making maintenance even more speedy (Note that there may be a few screws that require a 1.5mm or 2mm Hex Wrench). Tamiya Handy Starter and Glow Plug Heater are included for easy engine starts even for beginners (Handy Starter requires 7.2V battery pack, sold separately). ADSPEC GP 2-channel transmitter and TRU-03 receiver with fail safe device are included.

OPTION PARTS AVAILABLE SOON!

Both performance-enhancing and cosmetic Option Parts are planned for release in the near future. Keep an eye out especially for announcements of the 2-speed transmission that will increase top speed to 80km/hr (approx. 50mph) and powerful twin disc brakes.

MAKE NO MISTAKE

While the Nitrage shares the same 5.2cc engine and wheels/tires with the TNX 5.2R, they are only cosmetic similarities. This is a brand new chassis with a unique layout that has been designed specifically for off-road racing. Its lower ride-height means a lower center-of-gravity, giving the Nitrage superb cornering performance. Take a look at the pictures below to see the difference for yourself (TNX 5.2R on the left, Nitrage 5.2 on the right).
